What registries offer DNA program. If you have a stud that is only A.I. able or dead but has frozen sperm ,should he be DNA tested. And A question to you Jack,With BIG JOHN being so big were you worried about Screamer when she had his babies.If you don't mind could you go into that breeding and litter process please. Did she have them natural or C section and how many , pics would be awesome . Thanks and here is my future wacc-visegrip cross http://www.apbt.online-pedigrees.com/pu ... _id=203135
